【摘要】 沿郯城—庐江断裂带两侧各约500 km内发育的中生代以来白云母花岗岩、二云母花岗岩和A型花岗岩,五大连池、科洛和二克山火山岩带的强碱性富钾火山岩,高87Sr/86Sr值、低εNd值的中新生代玄武岩,沿郯庐断裂带两侧盆地广泛发育的磨拉石建造,稀土元素∑REE,∑LREE,∑LREE/∑HREE从老到新均逐渐增高;郯庐断裂带莫霍面深度明显大于两侧盆地;郯庐断裂带两侧地块的不连续与差异;沿郯城—庐江断裂带展布的华北地台北缘及东缘的高压麻粒岩、NNE向展布的日照、莒南、东海榴辉岩超高压带和安徽张八岭高压蓝片岩带;郯庐断裂带内表现的强烈挤压构造;郯庐断裂带东侧胶辽—苏北黄海负磁异常区不同于周围地质体(正磁异常区)等,所有证据都指示着南起安徽庐江,经山东郯城、黑龙江佳木斯,北至俄罗斯尚塔尔群岛的断裂带及其两侧构造带为一构造碰撞带:郯庐—尚塔尔碰撞带,郯庐—尚塔尔断裂带为碰撞带的缝合线。松辽盆地、华北盆地、苏北盆地等成煤、成油气等矿产的盆地是碰撞的结果。碰撞带的(突出)应力集中区鲁西—胶东超高压带碰撞区、燕山—辽东碰撞区是中国东部地震的高发区。碰撞的主要动力机制为日本海和鄂霍次克海的张开及菲律宾板块的俯冲。更多还原

【Abstract】 Muscovite granite,two mica granite and A-type granite developed within 500km on the either sides of Tancheng-Lujiang fault zone since Mesozoic Era,strong alkali and K-rich volcanics of Wudalianchi,Keluo and Erke volcanic belt and the Mesozoic-Cenozoic basalts with high 87Sr/86Sr and low εNd value and molasses formation developed in basins on the either sides of Tancheng-Lujiang fault zone are all characterized by gradual∑REE、∑LREE、∑LREE/∑HREE increment from the old to young;Moho interface bellow Tancheng-Lujiang fault zone is evidently deeper than that bellow basins on the either sides of the fault zone;blocks on the either sides of the fault zone are not continuous and uniform;high pressure granulite along the fault zone occurs in the north and east margins of the north China platform and"Rizhao-Junan-Donghai" ultra-pressure NNW eclogite belt and Zhangbaling high pressure blue schist belt in Anhui province;strong compression structure is developed in the fault zone;the Jiaoliao-Subei-Huanghai negative magnetic anomaly zone in the eastern Tancheng-Lujiang Fault Zone is contrast with the surrounding positive magnetic anomaly.All these are the evidences to lineate a tectonic collision zone extended from south at Lujiang,Anhui province,through Tancheng,Shandong province and Jiamusi,Heilongjiang province to north at Shangtaer archipelago in Russia.Tancheng-Lujiang fault zone is the suture of the collision zone.The major dynamic mechanism of collision is the openning of Japanese Sea and Okhotsk sea and subduction of Philippine Plate.更多还原
